auth context to check grant existence using entitledAccountIds, or separately
track supporting accounts excluded by nativeMainReadsForbidden, before
evaluating modelEligibleAccountIds. Ensure a blocked main account with
excludeAccountId set returns the temporary-unavailability message when it has a
confirmed grant, and add a regression test for this case.

Requesting changes on exact head 4fd2231e42b40c393d90895831fcbfea7c72637d.
The core direction is sound and the current implementation preserves the important trust boundaries: only a forwardable caller-owned bearer can become the one-shot alternate; stored Pool accounts remain preferred; exact-account and stored-401 retry budgets do not widen; excluding main cannot loop back to main; caller main does not enter Pool promotion, affinity, or health state; and Responses/compact both keep the replay bounded to one send. I did not find a remaining static credential-destination or retry-budget bypass.
Focused verification on this exact head under Bun 1.4.0 passed:
tests/codex-auth-context.test.ts: 67 passed, 0 failed;- the four new Responses/compact 429/402 caller-main cases: 4 passed, 0 failed;
- the lost-grant subagent case: 1 passed, 0 failed;
- typecheck and diff check passed.
Three merge blockers remain:
- This changes the OpenAI Pool credential-owner and failover contract, but
structure/08_openai-provider-tiers.mdstill says only that Pool owns the failover engine. Document the bounded caller-main alternate, including why it is allowed, why it never enters durable Pool state, and the exact-account/main-excluded/401-replay limits. A short Decision Log is appropriate for this auth-boundary decision. - Add fail-closed retry-level regressions for a gated model when the caller-owned main roster does not grant the model. The regular Responses and compact paths are separate implementations; each should prove that no caller-main send occurs and the first Pool rejection is preserved. The resolver unit test that main cannot loop back after
__main__exclusion is useful but does not prove either transport boundary. - The branch is four commits behind current
dev(15b0f701e). Rebase after the above changes and rerun exact-head CI. This auth-surface PR should receivemaintainer-sponsoredonly after those negative paths and the current-base result are green.
리뷰 · 우선순위 71 / 80설명 이 PR은 계정 게이트 모델에서 저장 Pool 계정이 거절된 뒤, 이미 검증된 요청 소유 main 자격을 alternate로 한 번 쓸 수 있게 합니다. "확인된 계정 grant가 없음"과 "확인된 grant 계정이 일시 불가"를 가르고, main 자체가 제외된 자격일 때는 main으로 루프백하지 않습니다. exact-account 선택과 저장 계정 401 refresh/replay 예산은 그대로입니다. affinity 진단에는 caller-owned main retry를 passthrough로 기록합니다. 지금 HEAD에서 Pool이 먼저 저장 계정을 고른 뒤 그 계정이 빠지면, alternate resolver가 제외 집합이 있다는 이유만으로 유효한 request-owned main까지 억누를 수 있습니다. 그 결과 로컬 401이 "이 모델을 지원하는 계정이 없다"고 말하지만, 같은 caller 자격에는 이미 grant가 있습니다. #2847 request-scoped main, #2889/#2897 pool 401, #3119 WHAM 401 위에 남는 구멍입니다. #3166/#3157 은 "건강한 핀이 소진 계정으로 persist 교체" 축이고, 이 PR은 "거절 후 alternate로 caller main 유지" 축입니다. 둘 다 파일은 auth-context, compact.ts, core.ts, 테스트 세 개입니다. +291/−8, MERGEABLE 입니다. fail-closed: caller 자격은 자기 roster로 확인하고, alternate send 한 번뿐이며, Pool affinity/승격에 들어가지 않고, main이 실패 자격이면 재사용하지 않습니다. types/config 분할 무관합니다. 점수는 71입니다. #3166과 함께 계정 라우팅 정합 열차입니다. 라인 src/codex/auth-context.ts excludeAccountIds/mainModelGrantUnobserved - main 제외와 pool 제외를 가릅니다. 테스트가 두 갈래를 모두 잠가야 합니다 메인테이너의 판단이 필요한 지점

Landed via maintainer carry #3180, merged to dev. All three of your commits were cherry-picked with author credit preserved. Why a carry: this branch was CONFLICTING against dev and a maintainer cannot push a rebase to a contributor branch. Worth recording, because it was checked rather than assumed: this is NOT superseded by #3166. That PR fixed initial selection — keeping a healthy request-owned main pin so Pool discovery does not persist an exhausted stored account before the first send. Yours is the post-rejection retry, and the gap was still in the landed tree: auth-context.ts refused the fallback on any excludeAccountId and compact.ts still dropped on !authCtx.accountId. Conflict resolution: #3176 had added a 5xx quota-outcome recorder inside the same no-alternate branch whose guard your change widens to admit main. Both were kept — the guard now excludes pool, main-pool and main, with the recorder inside it. The test conflict was purely additive and both authors' cases are retained; codex-auth-context.test.ts reports 70 pass, 0 fail on the carry head. The credential boundary you described held up under review. Thanks for the fix. |

Summary
Why
A request may arrive with a valid native Codex bearer while Pool routing first selects a stored account. If that stored account becomes unavailable, the alternate resolver excluded it but also suppressed the valid request-owned main credential merely because an exclusion was present. The resulting local 401 could claim that no eligible account supported the model even though the same caller credential already had a confirmed grant.
The fallback remains fail-closed: the caller credential is checked against its own authenticated model roster, is used for only one alternate send, never enters Pool affinity or promotion state, and cannot be reused when main was the failed credential.
